what is the correct way to get audio with ffmpeg for webrtc.

[serkansmg]

hi,
i am very new to oven media engine.
i am trying to steam webrtc and using ffmpeg inside server.
i want to stream both llhls and webrtc at the same time.

ffmpeg -f v4l2 -framerate 15 -video_size 1280x720 -i /dev/video0 \ -f alsa -i hw:1,0 -c:v libx264 -preset veryfast -b:v 2500k \ -c:a aac -b:a 128k -ar 44100 -f flv rtmp://localhost:1935/app/live
this is how i used to stream, i can get video on webrtc but not audio.
also i can get video but again not video on llhls ..

if i use obs studio. i can get audio from llhls but not from webrtc..
ps: hw:1,0 is correct audio device. i can record audio , ex:
arecord -D hw:1,0 -f cd -t wav -d 5 test_audio.wav

Server.xml.zip
this is my server.xml

and using docker by the way (also installed intel drivers etc.):
version: '3.8'
services:
ome:

container_name: ome
environment:
- OME_HOST_IP=192.168.0.3

- /test/ovenmedia/cert:/opt/ovenmediaengine/cert
devices:

restart: unless-stopped

so can anyone show me the correct way to get audio also using ffmpeg?

I think it is an issue related to OPUS encoding.
